Consider a beam with boundary conditions, loading, and cross-section given below. In addition to the applied concentrated moment, there is a compressive axial load, P = 5 kips that acts through the centroid of the cross-section. Determine the following: (a) The normal (flexural) stress, o, at D due to the applied moment. (b) The normal stress, o, (c) The total normal stress at D due to both the applied axial load and the applied at D due to the axial load moment.
